Game Worn NFL Helmets - 1 per season...right?

[Preston]

Hey guys,

So as a (somewhat) newer collector of game worn football helmets, it is [my understanding] that players are supposed to only wear one helmet per season (which is the primary reason team are not allowed to wear helmets to match throwback uniforms anymore). Is this correct?

The reason I ask........is because I am considering purchasing a game worn helmet from Fanatics of a player I've gotten to know. All of the Jaguars players in November have the military ribbon on the helmet like the Fanatics helmet, however all of the players in December have their helmets like my player in December (see right side of pic).

This makes me believe and wonder that some players (or teams) are choosing to use two helmets.
